tm-2 — Solanum lycopersicum

Summary

SOLYC09G018220.3, symbol tm-2, is a tomato gene on chromosome 9 that encodes a protein with NB-ARC, Rx_N, and LRR domains characteristic of plant disease resistance proteins, and it binds ADP, ATP, and metal ions. The gene is associated with defense responses, including response to virus, antiviral response, immune response, hypersensitivity, and the hypersensitive response programmed cell death (HR-PCD). It is also linked to viral transport, immune evasion, metabolic burst, autophagy, and protein folding. Beyond immunity, tm-2 is associated with fruit ripening, pollen germination, oviposition, heterosis, and sugar content. The encoded protein localizes to the membrane, plasmalemma, and cytoplasm. Studies of related genes in other species further link the family to pathogen recognition.
